    t1lib vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    t1lib could be made to crash or run programs as your login if it opened a
    specially crafted font file.
    Software Description:
    - t1lib: Type 1 font rasterizer library - runtime
    Jonathan Brossard discovered that t1lib did not correctly handle certain
    malformed font files. If a user were tricked into using a specially crafted
    font file, a remote attacker could cause t1lib to crash or possibly execute
    arbitrary code with user privileges.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 11.10:
      libt1-5                         5.1.2-3ubuntu0.11.10.1
    Ubuntu 11.04:
      libt1-5                         5.1.2-3ubuntu0.11.04.1
    Ubuntu 10.10:
      libt1-5                         5.1.2-3ubuntu0.10.10.1
    Ubuntu 10.04 LTS:
      libt1-5                         5.1.2-3ubuntu0.10.04.1
    After a standard system update you need to restart your session to make
